Okay thanks to this post I understood memoization (a word almost impossible to type with autocorrect on btw), and realized I was actually using it while not understanding the term, that might prove useful! This simple optimization reduces time complexities from exponential to polynomial. For example, once our algorithm checks the value of the first array item, 8, it will then scan the remaining values for 3 (e.g., 11 8 = 3).

Optimal control requires the weakest assumptions and can, therefore, be used to deal with the most general problems. Short answer: a) (3pts) Huffman coding is a Dynamic Programming problem. There `value(i,j)=min( value(i-1,j),value(i,j-1) )` so you make a wavefront for values as you progress through `i,j` space. ?|DD?qsv'Mj0v4bmNzG{Lw Qy-rI'CC++hs,s9fDI#sCEDS@I*Qjd]r'z:=\Pf,\tH0=*k'a,ycu^u{?$q:R`5xFq6qH3$Q%M>")3h}zF>$&F|gy9_nT-W~kVz}Y5Yo8cm;/

Find the length of the longest increasing subsequence inside a given array. A well-known example of recursion can be seen with the Fibonacci sequencea numerical sequence made by adding the two preceding numbers (0, 1, 1, 2, 3, 5, 8, 13, 21, etc): When examined, our code is error-free and works as expected.
